If you are, I would greatly appreciate it if you could tell me how much gain you are using and how far away the link is from the centre of servo horn.

I have a problem in that it seems to be holding a heading really well but if I input a rudder command the heli moves fine but when I stop the command the tail moves back the other way a little. It seems to do this more on one way than the other (understandable I guess).

Other than this problem the tail is almost rock solid!

I am using a pretty lame servo (next one up from 3003 I think) but I'm sure it should be working better than it is. I know the HLG 200 isn't the best gyro either but again I'm not asking a lot from it- I'm not past fff yet!

yea im useing one m8 in fact i got one on my 50 hyper

mine is about 14mm from center
14-14.5 will be fine
make shaw you set the center with out the gyro in line ie 4.5mm gap at tail.
check that tail linkage is smooth and not binding

then turn the pot just over halfway
just spool it up to it gos light to make shaw there enouthg gain
before you go to far its easy not to enotgh gain with a screw pot
and it better too have too much gain that you can turn down
than not enoutgh

then get the enging tuned up back down the pot untill the tail stops waging in a hover

just go slow and a bit at a time to it feels right

later when you do some fast turns it may wag a touch then then just back gain down a tiny touch untill that stops

remember thease thing have a pot and it needs a gental touch on screw to get right it easy to go to turn it a touch and go to far and have to come back againg.
they can be a pain to get spot on its not as easy to as a tx controled guro that you can chage a 1 or 2% at a time with the radio.

make shaw you enging is tune ok
if it too rich it can affect the tail
and when it does it ushally the low end that need leaning a bit
